Don't be fooled by the first-class energy efficiency when buying air conditioners.

Although the first-class energy efficiency represents more energy saving, the evaluation of an air conditioner should not be fooled by the first-class energy efficiency. When buying air conditioners, you need to pay attention to the following three key points.

First of all, the energy efficiency grade is only an indicator, not the whole. Energy efficiency grade is an index to evaluate the energy utilization efficiency of air conditioning, which is usually divided into grade one, grade two and grade three.

The first-class energy efficiency means that the energy utilization efficiency of air conditioners is the highest, followed by the second class, and so on.

However, the energy efficiency grade is only an index to evaluate the energy consumption of air conditioners, and it is not possible to judge the cost performance of an air conditioner simply by the energy efficiency grade.

In practical use, factors such as cooling/heating effect, service life and brand reputation of air conditioners need to be considered.

Secondly, although the energy efficiency of some air conditioners is Grade II, the technology is more advanced. In order to achieve a higher level of energy efficiency, these secondary energy-efficient air conditioners adopt more advanced technologies and materials.

These technologies include high efficiency compressor, frequency conversion regulation, intelligent control and so on. , temperature and operating power can be adjusted more accurately, thus achieving more efficient energy utilization.

Although the price of secondary energy-efficient air conditioner is relatively high, it can bring lower energy consumption and more comfortable experience after long-term use.

Finally, brand, quality and function are also the key factors to determine the cost performance of air conditioners. Take the compressor as an example. Japanese brands such as Daikin, Mitsubishi and Toshiba have mastered the core technological advantages, but there is still a certain gap between domestic compressors and imported brands.

Is it better to buy a second-class energy-efficient air conditioner or a first-class energy-efficient one?

If you care more about the quality and experience of air conditioning, it is no problem to choose a secondary energy-efficient air conditioner with good quality, because there is little difference in energy-saving and electricity-saving effects. But generally speaking, the first-class energy efficiency is preferred under the same quality, especially the air conditioner with the new first-class energy efficiency standard. Moreover, domestic air conditioners represented by Gree are not inferior to foreign brands in product quality, and their cost performance is higher.

For example, the Yunjin II series of Gree Air Conditioning is an air conditioner with excellent configuration, which meets the new national energy efficiency standards, and the energy efficiency ratio APF value is as high as 5.27. Using Lingda compressor, the copper tube of L-shaped condenser has larger outer diameter, solid material, fast cooling and heating speed and good mute effect during operation.

The fuselage lines are soft and full of beauty, which makes it look fashionable in the bedroom. In terms of functional design, Gree Yunjin II supports up, down, left and right scanning and 7-speed wind speed adjustment. It also has four sleep modes, quiet, energy-saving and comfortable.
